Definitely a 750 flywheel. I confirmed the number from my 750 flywheel laying in the garage.
Coil looks like it's from a Yamaha but if the black screw covers were on the plug wires, I'd say it came from the Kawi e-box. Coil part number is not the same as my 701 SJ e-box.That e-box is similar in a way but no way it's from a 750. The CDI has the same color wires as my 701 e-box but the P/N on my SJ CDI is F8T13174 instead of *72...maybe it's a 6m6 cdi but I don't know. The starter relay looks identical to my Yamaha e-box.
